Hi everybody,

This is what I see when I inspect the element:

<div class="alert alert-danger">
                                <i class="fa fa-exclamation-circle fa-2x"></i>
                                Username or Password is incorrect.
                            </div>

However, I do not see the icon at all and I see it 0px * 0px. Do you know what is wrong in this markup and why I don't see the error sign?

Thanks in advance.
